Abstract

Apparatus for the continuous extrusion of metals in which feed is introduced into a pair of circumferential grooves 4 (Figure 4) in a rotating wheel 2 to contact arcuate tooling 14 and abutments 24. The feed is constrained by the abutments 24 to flow through exit apertures 32 in a die top 28 from the respective grooves 4 to a substantially toroidal chamber 34 around a hollow, open ended, portal mandrel 42 to extrude through an annular die orifice 38 as a cladding for a continuous core 44. Cooling air may be supplied to the interior of the cladding, which is subsequently swaged down on to the core. A solid mandrel may be utilised where it is desired to extrude tube.
